AN EASY but effective force for stage or platform work can be made with the Svengali pack. An unprepared easel is required which has a ledge on which you can stand seven or eight packets of cards. Having shuffled and cut the prepared pack, show the faces all different. Next, while exhibiting and setting up the easel, invite a spectator to call a number between five and ten. Cut that number of piles from the pack, placing them face out on the easel. Call attention to the fact that all the cards are different and then turn all the packets with their backs outwards. The top card of each packet is a force card so it makes no difference to you which of the heaps is selected.
